ravines There is little doubt that this hystricomorph lived in the Pleistocene and such an interesting find leads one to hope that additional researches in Ecuador will bring to light more of the members of the preceding epochs am indebted to Dr W D Matthew, Curator of the Department of Museum, both for permission to describe material which belongs in his department and for helpful discussions I Palaeontology of the American this upon thp material itself Drytomomys, new genus A large hystricomorph rodent with very heavy incisors which have a thick cutting edge of enamel; molars rooted but fairly hypsodont, crown pattern made up of a series of deep reentrant loops which become isolated by wear to form enclosed lakes, the normal number of which is three There is a very deep fossa in the lateral face of the premaxillary Genotype: Drytomomys sequaiorialis Drytomomys sequatorialis, Type: No 13219, Department new species of Vertebrate Palaeontology, del Azuay, Ecuador, near the hacienda of Serior Carrasco, from Nabon, Prov the bones from who took the cave The type is a fragmentary skull, only the anterior portion of the cranium, carrying four molar teeth, and the anterior portion of the mandible, all of the teeth present Accompanying these parts of the skull are a few fragments of limb bones, etc — Description General proportions of cranium unknown; a very dee]) and apparently extensive fossa is indicated as lying in the lateral face of the rostrum, partly in the premaxillary, partly in the maxillary; incisive foramina probably of mandible robust and heavy, typically hystricomorph; incisors, upper and and strong, proportionally enormous, rather deeper than broad and with well-developed cutting edge of heavy enamel molar teeth rooted but with high crowns, four in each jaw; molar pattern simple, formed by a series of reentrant loops of enamel which enter from the inside in the case of the upper molars, externally in the lower series; in the state of wear shown by the type most of hese loops have been cut off to become completely detached lakes, elliptical in outline, while the tooth is sub-columnar in shape, completely encircled by enamel with scarcely any race of the entering loop which was ancestral to the lake; true molars with typical pattern of three loops or lakes, lower premolars with two main lakes and three (lefl or four fair size; lower, very

8.8X7.5; breadth of upper incisor, 8.4; depth of breadth of lower incisor, 8.4; depth of lower incisor, 10.2 incisor, 10.7; Drytomomys may be readily distinguished from all living rodents excessively developed incisors and by the molar pattern of completely isolated enamel lakes While the skull is of about the same size as in the genus Castor, the incisors are actually twice as heavy and the enamel cutting edge is conspicuously heavier It was because of this highly developed chisel-like incisor that the new genus was named Drytomomys, from the Greek dpvronos, a wood cutter and nvs, a mouse If I ain correct and this rodent was a woodcutter, it was even better equipped than the beaver, and bearing out this assumption is the by its presence of the deep lateral fossa of the rostrum which undoubtedly mark the attachment area Apparently Myocaster its of a greatly developed masseter muscle closest affiliations with living rodents are The molars of this genus, in the worn with show a fairly genus However, stage, close approximation to the condition seen in the fossil Myocaster molars have an extra reentrant, internal in the upper series, external in the lower, which the Drytomomys tooth lacks A specimen of Myocaster (No 42751) has a the new molar toothrow equal in length to that of genus, but the incisor teeth are about half as heavy Among fossil genera, Neoreomys is similar in many details to the Ecuador rodent but differs from it in the same characters as does Myocastor In fact Neoreomys resembles Myocaster more closely than it does Drytomomys No other genus of the Santa Cruz fauna bears as close a relationship to Drytomomys as does Neoreomys, but Drytomomys is so obviously related to this genus that it would appear perfectly at home in any collection from the Santa Cruz formation The fragments of limb bones present, the head of a humerus, distal end of an ulna, head of a femur and badly broken distal end of a tibia, These limb bones all indicate an animal of robust and heavy build are very much larger than those of Myocaster and only a little less robust than those of Hydrochoerus AMERICAN MUSEUM NOVITATES No 36 THE GENUS PANURGINUS OBTAINED BY

Nylander thought that the lack of When had not seen P nor have any additional specimens been collected, so far as I The am not in the British Museum, at Oxford, or in any The precise definition of Panurginus, of the American collections therefore, remains somewhat uncertain, though it is probable that P aware species is we now understand it Morawitz in 1876 founded a genus Epimethea on certain species differing from Panurginus in having yellow tegumentary markings on the abdomen and other parts of the body E variegata F Morawitz may be taken as the type It is recorded as occurring in the Caucasus and in Algeria Probably Epimethea should be recognized as a genus but, although I have seen E variegata in the British Museum, I have never made a close examination of any species of this group In 1894 Gribodo based his genus Scrapteroides on S difformis Gribodo, which is now considered identical with Panurginus albopilosus (Lucas), a species of Spain and Algeria I possess this species and find that it has a black face in the male and that the first recurrent nervure falls considerably basad of the first intercubitus (transversocubital) In these respects it resembles our American P atriceps (Cresson), but niger belongs to the genus as F the latter has a Panurginus Regions If panurgus, we much is longer flagellum in the male confined to the Palaearctic, Nearctic, and Neotropical

caliente" of Mexico (P bidentis Cockerell) and in Brazil (P solani Ducke) Nevertheless, the strictly tropical species are not very numerous If we are surprised that the Central European P montanus has not produced any segregates, we must note that our closely analogous species, P cressoniellus, is also without a series of closely related forms These bees are indiscriminate feeders on a considerable series of flowers, and it appears to be true that oligotropic habits favor the evolution of new species We know that species of Greehyella and Hypomacrotera are oligotropic and there are reasons for regarding several species of Panurginus as such, but the subject requires much more minute study In general sweeping, it is easy to obtain from a clump of flowers bees which were not actually feeding on the flowers cited, and even oligotropic bees wander from their proper plants at times The collections of Dr Lutz greatly increase our knowledge of the species and distribution of western
